Improved scraper

Letters Patent No. 93,000, dated July 27, `10869.l

IMPnovnn saneren.

The Schedule referred tov in these Letters Patent and making part of the same- .To all whom it may concern:

same, reference being had to the accompanying draw-` ings, and to the letters of reference marked thereon.

rIhe nature of my invention is to provide a reversilble scraper, for the more rapid and cheap construction of highways, turnpikes, and railroads, so that the crown of the street or roadway may be formed on the line of travel by the machine, without the necessity of hauling the earth transversely from side to side.

. To accomplish this object, I ,employ a curved scraper, that is connected by hooks and eyes to the rear cfa stout frame, which is mounted on wheels.

A fiat, curved har extends around the back vof the s)craper, conforming to its shape, and acting as a race.

The bar also forms a semicircular plate betweenthe scraper and frame.

Holes are pierced vin the plate for connecting and extension-rods.

A fiat bar is pivoted to the top of the scraper, and extends to the rear cross-beam of the frame, passing under the semicircular plate, to which it is connected by a strap.

By this construction, the scraper is changed to run at the angle desired.

Referring to the drawings for a better illustration of my device, the figure represented is a planA or top view of my nrachine.

A is a stout frame, mounted on two driving-wheels, and vbolted to the axle and neap.

To the rear end of the frame, onu| plaire with the top of the axle, is bolted a stoutross-beam, B, and

through it eye-bolts ct a a' a a pass, for connecting the E, is formed between the cross-beam of the frame and top of the scraper, the arms of which extend around the back of, and arel bolted Ato the scraper.

Between these arms is also `bolted a brace,-F, the

top ofv which forms a pivot, F', for the transverse draught-bar G, which passes under the turn-plate, to

which it is connected by a strap, G', and hooksinto the eye-bolt a on the cross-beam of the frame.

At each end of the scraper are bolted braces H H, which extendto the turn-plate, and to which they are also attached by'bolts. By this means the scraper is firmly braced, and no ordinary strain can affect it on the line of travel, even if it is made of thin boiler-iron.

Each of thevside-braces is pierced about midway, for the connecting and extension-rods I I 1; and when it becomes necessary to change the angle ofthe scraper from one side of the road to the other, the rod I is removed to the opposite end, to occupy the position of the extension-rod I; .and one end of this rod is hooked in the eye-bolt adjoining, and the other end is placed in one of the eye-holes b on the turn-plate, after the transverse extension-rod I has been removed.

The .extension-rod I is now placed in the eye-bolt and eye-hole, which the stay-rod I before occupied, and the desired angle to the scraper is obtained.

The scraper, however, can he made to run more or less right or left obliquely, by lengthening cr shortening the rod I I', and changing the hook on the end of the rod I", from one graduated hole b b, t0 another on the turn-plate.

This rodacts as. anoblique strengthening-rod, and prevents the scraper from swaying or moving laterally; and another rod of the like character may be em ployed at the opposite end, the one crossing the other on the turn-plate.

-Inconstructing railroads and turnpikes, where the ditch is to be cut deep, the cross-beam at the rear 4of the frarne may be lengthened, and extend beyond the reach of the wheels, and' to it be attached extra motive-power, to assist in the side or end-draught.

This' end of the scraper may also be weighed; usually the weight of one man on the handles c `c -will be sufficient.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

The scraper described, consisting essentially of the carriage A, draught-bar G, semicircular turn-plateE,

and scraper O, the whole being combined substantially in the manner and for the purpose described.

In witness whereof, I have hereunto set my hand I and seall TIMGTHY G. PHELPS. [L. S.]
